About this app
Crack your next DSA interview by practicing in the moments you would have scrolled.
DSALock turns phone distraction into focused interview reps. Every time you open Instagram, YouTube or any app you choose, it asks you one quick question first. Answer a data structures and algorithms rep, then get on with your day. Small reps, many times a day, add up to real interview preparation.
WHY DSALOCK
Most people do not fail the DSA round because they cannot learn it. They fail because they never practice consistently. DSALock builds the habit for you. It locks the apps you pick at the times you set, and the only way through is a rep. You learn DSA in the exact moments you used to lose to scrolling.
WHAT YOU PRACTICE
A full computer science interview curriculum, not just arrays:
• DSA: arrays, strings, two pointers, sliding window, binary search, recursion, trees, graphs, dynamic programming, heaps and tries
• Low Level Design and OOPs concepts
• DBMS and SQL
• Operating Systems
• Computer Networks
• Aptitude and puzzles
Every card is a short rep with a recall question and a clear explanation, so the concept actually sticks.
HOW IT WORKS
• Pick the apps to guard and the times they lock
• Choose your intensity: steady, balanced or beast
• Get one rep each time you reach for a distraction
• Spaced repetition brings back what you got wrong
• Track your daily goal and streak
WHO IT IS FOR
• Students preparing for campus placements
• Working engineers switching to product based companies
• Anyone preparing for SDE, software engineer or computer science interviews
• Self taught developers who want structure
Whether you want to learn DSA from scratch, brush up data structures and algorithms before an interview, practice coding every day, prepare for a computer science interview, or build a steady placement preparation habit, DSALock keeps you sharp without booking a separate study session.
Stop doomscrolling. Start repping. Your next interview round starts now.
Accessibility Service Usage:
DSA Lock uses the Android Accessibility Service only to detect when you open apps that you have chosen to block. When a blocked app is detected, a computer science concept or a problem is displayed to encourage learning and interview preparation.
The service only monitors which app is in the foreground. It does not read, collect, or share any screen content, personal data, or keystrokes. All data remains on your device.
You can disable the Accessibility Service at any time in your device settings.
